I think it's been mentioned that right now, the team is anxious to prevent people from clearing A savage in penta-melded, crafted gear. I don't t think that would be the case among all raiding FCs but the top tier ones would have the resourced to do that. One idea I liked from WoW was the self only crafts that in some cases, were as good as mid tier raiding gear. Those would needed to be gated behind specializations though.

Personally, I'd like crafting to be like DAoC's crafting system, where it's not possible to min max any one thing. There's caps on stats like vit and dex, but there's also combat bonuses like attack speed, crit chance, etc, which have caps. You have to make tradeoffs, and it's based on your play style. It helps that DAoC has greater character customization then FFXIV, but I think there's room for a sch who wants to cap crit chance for Adlo vs one that want's to cap spell speed for faster heals.
